How to fetch youtube channel list of loggedin user - youtube-api

I want to fetch the youtube channel list and show it on tableView can anyone help to get the channel list of loggedin user via google.

You may want to check the Channels: list method which returns a collection of zero or more channel resources that match the request criteria. Then use the forUsername parameter.
The forUsername parameter specifies a YouTube username, thereby requesting the channel associated with that username.
Additional reference:
YouTube API v3 get all channels associated with a logged in user

Liked videos for a set of users via YouTube data API

For a given list of users (via their email address), I am interested in getting their most recent liked videos.
Also what is not clear is - is it possible to access any liked videos for users for which you don't have authorization?
I have seen solutions via getting the 'Liked' playlist, however it appears this can only be accessed for myself.
Note that a given user's list of liked videos -- of which playlist ID indeed can be retrieved via Channels.list API endpoint through the property contentDetails.relatedPlaylists.likes -- is private data pertaining that user.
Hence you're not going to be able to obtain from the API the kind of information you're looking for -- except if you issue an authorized API endpoint call, implying that the respective call is to be made relative to your own YouTube account (i.e. channel), in which case you'll get the ID of the playlist of videos that you liked yourself.
There's also the possibility of employing the parameter onBehalfOfContentOwner -- applied to each of the API endpoints Channels.list and PlaylistItems.list:
onBehalfOfContentOwner (string)
This parameter can only be used in a properly authorized request. Note: This parameter is intended exclusively for YouTube content partners.
The onBehalfOfContentOwner parameter indicates that the request's authorization credentials identify a YouTube CMS user who is acting on behalf of the content owner specified in the parameter value. This parameter is intended for YouTube content partners that own and manage many different YouTube channels. It allows content owners to authenticate once and get access to all their video and channel data, without having to provide authentication credentials for each individual channel. The CMS account that the user authenticates with must be linked to the specified YouTube content owner.
For thorough info about these things see the document Acting on behalf of a content owner, specifically the section relative to YouTube Data API v3.

YouTube Data API returns channel for user without channel

I've got a YouTube user, which doesn't contain a YouTube channel. But the YouTube data API does return a channel, if I query the youtube.channels.list API method by using the "mine=true" attribute like in following example (1).
Example:
(1) Returns a channel (mine=true; by using OAuth):
https://developers.google.com/apis-explorer/#p/youtube/v3/youtube.channels.list?part=snippet%252CcontentDetails%252Cstatistics&mine=true&_h=5&
This query (1) returns a channel which contains a channelId. Now I'm trying to query for the playlists of this channel by using the previously returned channelId.
(2) Returns a 404 "channel not found" error
https://developers.google.com/apis-explorer/#p/youtube/v3/youtube.playlists.list?part=snippet&channelId=UCIReEy02ibumfYhQP3-0drQ&_h=4&
As described here it's possible to use a YouTube account without a channel but with limited functionality like using playlists:
With a Google Account, you can watch and like videos and subscribe to channels. However, without a YouTube channel, you have no public presence on YouTube. Even if you have a Google Account, you need to create a YouTube channel to upload videos, comment, or make playlists. You can use a computer or the YouTube mobile site to create a new channel.
What's the reason query (1) is returning a channel even if a YouTube account doesn't contain a channel?

[1] Returns a channel (mine=true; by using OAuth):
Because of every account on youtube itself a channel. They can do all the things they want like any channel can do e.g. upload videos. Also, we can make multiple channels under the same account.
[2] Doesn't return a channel (forUsername=UCIReEy02ibumfYhQP3-0drQ; by/without using OAuth):
Please make sure UCIReEy02ibumfYhQP3-0drQ is a valid username
I'm building something with the YouTube API. I've found a few oddities so far. The first thing is that a channel can have a title of 'blah blah - Topic' so you probably want to screen those out if you want to retrieve channels with their own content. If I'm right in my thinking, these are just channels with Playlists. Example: https://www.youtube.com/channel/UC6tQSWkTxbPNaJ_LQ-Ia6jQ/
Also be aware that channels don't have to have a unique title.
Finally there are many channels that return nothing from the API Channels.List method, even though they are channels. I'm still figuring these out. I don't think they are returned from searching through the API, but if you get your Channel IDs from another source then this could be an issue.

Archival lists of most subscribed YouTube accounts?

Is there a way to find the top X YouTube accounts by subscriber count for Y year---say, the top 100 accounts in 2015? I don't see anything in the API docs, and while there are services like SocialBlade and VidStatsX, they don't provide archived lists, and the data is not captured on archive.org.
The standard Analytics API doesn't provide this functionality. You can get data about views, likes, and dislikes, but you must provide one or more channel IDs.
Required Parameters: ids
Identifies the YouTube channel or content owner for which you are
retrieving YouTube Analytics data.
To request data for a YouTube
channel, set the ids parameter value to either channel==MINE or
channel==CHANNEL_ID, where CHANNEL_ID identifies the currently
authenticated user's YouTube channel.
To request data for a YouTube
CMS content owner, set the ids parameter value to
contentOwner==OWNER_NAME, where OWNER_NAME is the CMS user ID for the
user.
Use the Try this API section on the reference page to test the possibilities.

How do I get a list of YouTube channels, and associated channel URLs (user or channel), owned by an authenticated user

We use the following call to get ChannelID's for an authenticated user and it works well for most cases. Some YouTube user connect their channels to a Google+ page and this fails for one of our users in that situation. In that case, the call only returns the channelID associated the user's email account used for authentication, not all channels owned by the user.
System.IO.Stream resultStream = service.Query(new Uri("https://www.googleapis.com/youtube/v3/channels?part=id%2Csnippet%2CcontentDetails%2Cstatistics%2CtopicDetails&mine=true&key=" + GlobalSettings.developerKey));
Also, we construct the channel URL by appending the channelID to the following URL.
http://www.youtube.com/channel/
However, some channels us a user name and path instead of channelID. How can I detect that the type is user instead of channel? In that case the user name is appending to the following path. The Google+ user's main channel uses this path with a user name.
http://www.youtube.com/user/
A few things:
In v3 of the YouTube Data API, you're forced to work with channel ids everywhere. This is a good thing. Channel ids are the only universal way of identifying channels! Legacy usernames used to serve that purpose as well, but the number of channels without legacy usernames is increasing by the day, so writing new v2 code that relies on legacy usernames is not recommended (and isn't possible in v3).
When making a channels.list(..., mine=true) call, you're always going to get back exactly one channel. The channel you get back will depend on which channel was chosen when you went through the OAuth 2 flow—there's a picker within that flow that lets you choose whichever channel you'd like if your Google Account happens to have access to more than one channel. If you want to operate on a different channel, you need to explicitly obtain an OAuth 2 token for that channel.
channel.list(..., managedByMe=true) can return multiple channels, but that API call is only relevant to YouTube content partners, and is used hand-in-hand with the onBehalfOfContentOwner parameter. Most developers can safely ignore this unless you know you're explicitly working with YouTube content partners' accounts.
The URL to visit a channel's page isn't returned anywhere in the v3 API response—that's true, and maybe it should be (feel free to file a feature request). If you want to manually construct the URL, you can use http://www.youtube.com/channel/CHANNEL_ID, where CHANNEL_ID is the standard UC... value that is used everywhere else in v3. That should produce a valid URL regardless of whether there's also a legacy username for the channel.
The only way that I have been able to do this is to use the v2 API, instead of v3. Specifically, you can use the same OAuth token, but access this API endpoint:
https://gdata.youtube.com/feeds/api/users/default?v=2
It will return an XML doc that contains both a URL to the user's channel (using the channel id), as well as the YouTube username.
See https://developers.google.com/youtube/2.0/reference#User_profile_entry for more info.

Can Youtube v3 API be used currently for retreiving data of channels that user is not associated with?

I want to know if we can use Youtube V3 API to retrieve channel data, videos etc when the channel requested is not the authenticated user's own channel.
The documentation for v3 youtube api (https://developers.google.com/youtube/v3/docs/channels/list#try-it) says "The list method returns a collection of zero or more channel resources that match the request criteria. At this time, this method does require an authenticated user, and the API only supports requests to retrieve information about the channel that is associated with the currently authenticated user."
Example in V2 it is http://gdata.youtube.com/feeds/api/users/{user_name}, what is the equivalent in v3 ? Is it available yet ?
You can request a channel by ID e.g. Lady Gaga channel:
https://www.googleapis.com/youtube/v3/channels?id=UCNL1ZadSjHpjm4q9j2sVtOA&key=AIzaSyCR5In4DZaTP6IEZQ0r1JceuvluJRzQNLE&part=snippet,contentDetails
The plan is to support retrieving both channel profile information and the ids for the uploads/favorites/playlist/etc. feeds for a given channel in v3. It's not quite yet supported, but should be around the time of the public launch. (Which, I can't commit publicly to a date for that at this time.)
